not a right triangle
a=9
b=16
c=20
a^2+b^2=c^2
81+256=337
20^2=400

The measure of three sides of a triangle are 9,16, and 20 determine whether the triangle is a right triangle. Explain your answer
------
It's a right triangle if it satisfies Pythagoras.
Checking c^2 = a^2 + b^2
------
20^2 = 9^2+16^2
400 = 81 + 256
400 = 337
---
False:: So it is not a right triangle.
